Uma kukhulunywa ngezinto zokuvala, kunezinhlobo ezintathu eziyinhloko zama-sealants ezivame ukusetshenziswa ezinhlelweni ezahlukahlukene:i-polyurethane, i-silicone, futhiI-latex esekwe emanzini. Ngayinye yalezi zinsimbi zinezakhiwo ezihlukile futhi ifanele ukusetshenziswa okuhlukile. Ukuqonda izici zalezi zinsimbi kubalulekile ekukhetheni uphawu olufanele lwephrojekthi ethile.
I-polyurethane sealantszaziwa ngokuhlala kwazo okukhethekile nokuvumelana nezimo. Zivame ukusetshenziselwa ukwakhiwa kanye nezicelo zezimboni lapho kudingeka uphawu oluqinile, oluhlala isikhathi eside. Ama-polyurethane sealants ayakwazi ukumelana nesimo sezulu, amakhemikhali, futhi ayakwazi ukumelana nemihuzuko, okuwenza alungele ukusetshenziswa ngaphandle. Bayakwazi futhi ukunamathela ezintweni ezihlukahlukene, kuhlanganise nokhonkolo, ukhuni, insimbi nepulasitiki. Ngaphezu kwalokho, ama-polyurethane sealants anokumelana okuhle kakhulu nemisebe ye-UV futhi afanele ukuvala amalunga nezikhala ezakhiweni zangaphandle.
Ama-Silicone sealantszithandwa ngokunamathela kwazo okuhle nokuvumelana nezimo. Zivame ukusetshenziswa ekusetshenzisweni kwamapayipi, izimoto kanye ne-elekthronikhi ngenxa yokumelana nomswakama kanye namazinga okushisa aphezulu. Ama-Silicone sealants ayaziwa nangokukwazi kwawo ukuhlala eguquguquka ebangeni elibanzi lokushisa, okuwenza afanelekele ukusetshenziswa ngaphakathi nangaphandle. Ziphinde zimelane nokukhula kwesikhunta nokukhunta, okuzenza zilungele ukuvala amalunga ezindaweni ezinomswakama njengezindlu zangasese namakhishi. Ngaphezu kwalokho, ama-silicone sealants anezakhiwo ezinhle zokuvikela ugesi, okuwenza afanelekele ukuvala izingxenye zikagesi nokuxhuma.
Ama-latex sealants asekelwe emanzinizaziwa ngokusetshenziswa kwazo kalula kanye nokupenda. Zivame ukusetshenziselwa izicelo zasendlini ezifana nokuvala izikhala nokuqhekeka ezindongeni, amafasitela neminyango. Ama-latex sealants asekelwe emanzini kulula ukuwahlanza ngamanzi futhi anephunga eliphansi, okwenza afanelekele ukusetshenziswa endlini. Angaphinda apendwe ukuze ahlanganiswe ngaphandle komthungo nezindawo ezizungezile. Nakuba ama-latex sealants asekelwe emanzini angase angapheli njenge-polyurethane noma ama-silicone sealants, ayisinqumo esihle kakhulu samaphrojekthi okuvalwa kwangaphakathi lapho ukusetshenziswa kalula kanye nobuhle kubalulekile.
Kafushane, i-polyurethane, i-silicone, ne-latex sealants esekwe emanzini ngayinye inezindawo ezihlukile futhi ifanele ukusetshenziswa okuhlukile. Ama-polyurethane sealants aziwa ngokuqina kwawo kanye nokumelana nesimo sezulu, okuwenza alungele ukusetshenziswa ngaphandle. Ama-Silicone sealants aziswa ngokuguquguquka kwawo kanye nokumelana nomswakama kanye namazinga okushisa aphezulu, okuwenza afanelekele uhla olubanzi lwezicelo. Ama-latex sealants asekelwe emanzini kulula ukuwasebenzisa, ayapendeka futhi anephunga eliphansi, okuwenza alungele amaphrojekthi okuvalwa kwangaphakathi. Ukuqonda izici zalawa ma-sealant kubalulekile ekukhetheni uphawu olufanele lwephrojekthi ethile.
